In this installment in our series on the basics of divers’ replica watches, we explain why some dive replica watches have built-in helium-release valves and why others don’t. We also explain why each type is perfectly OK, depending on the type of diving you do.
Comparing “diving” as most people know it to “saturation diving” is a bit like comparing an amateur bicyclist to a professional construction worker. They might share the same environment and the same need to breathe, but other than that, they are in fact doing quite different things (this applies to most types of diving, by the way). Saturation diving (meaning the diver’s tissues have absorbed the maximum of gas possible) was practically explored at the end of the 1930s in order to (A.) reduce a diver’s risk of decompression sickness when (B.) working at great depth for (C.) long periods of time — in other words, to increase both effectiveness and safety.
